A method for preparing continuous bamboo fibers, which relates to a technical field of bamboo fiber preparation. The method includes processing bamboo raw materials into reticulated bamboo fiber tapes, screening the bamboo fiber tapes, dividing the reticulated bamboo fiber tapes with different properties according to product requirements, performing high pressure splitting on the reticulated bamboo fiber tapes which conforms to a screening condition, separating the bamboo fibers with different slenderness ratios from the bamboo fiber tapes after the high pressure splitting is performed, forming a partial oriented bamboo fiber mat with uniform density by the bamboo fibers, forming an oriented bamboo fiber bundle with uniform linear density by the bamboo fiber mat, twisting the bamboo fiber bundle to form a bamboo fiber yarn, forming a rope by the bamboo fiber yarn, and forming a spindle based on a specifications.

A screw feeder includes: a case that includes a material putting-in portion through which a fluff material is put in and a material putting-out portion through which the fluff material is put out below the material putting-in portion; and a screw that includes a rotational shaft and a blade portion, the rotational shaft being provided rotatably inside the case, the blade portion being spirally mounted on the rotational shaft; wherein the screw is rotated with repeated alternation of a slope-down direction in which the blade portion slopes downward spirally in a vertical direction and a slope-up direction in which the blade portion slopes upward spirally in the vertical direction.
